Official Title: A Multi-Center Phase Ib Study of Oxaliplatin (NSC #266046) in Combination With Fluorouracil and Leucovorin in Pediatric Patients With Advanced Solid Tumors

Brief Summary: This phase I trial is studying the side effects and best dose of oxaliplatin when given together with leucovorin and fluorouracil in treating young patients with advanced solid tumors. Drugs used in chemotherapy, such as oxaliplatin, leucovorin, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells.

Detailed Summary:

PRIMARY OBJECTIVES:

I. Determine the dose-limiting toxicities (DLT) and maximum tolerated dose (MTD) of oxaliplatin when given together with fluorouracil and leucovorin calcium in pediatric patients with recurrent or refractory solid tumors, including tumors of the CNS.

SECONDARY OBJECTIVES:

I. Determine the pharmacokinetic properties of oxaliplatin in this pediatric patient population.

II. Correlate alterations in accumulation of fludeoxyglucose F 18 with tumor response in those patients who can readily undergo a positron emission tomography (PET) or PET/CT scan.

III. Assess the safety profile of this regimen in these patients. IV. Evaluate any preliminary evidence of anti-tumor activity of this regimen in these patients.

OUTLINE: This is an open-label, multicenter, dose-escalation study of oxaliplatin. Patients are stratified according to solid tumor type (non-CNS vs CNS).

Patients receive oxaliplatin IV over 2 hours and leucovorin calcium IV over 2 hours on day 1 followed by fluorouracil IV continuously over 46 hours on days 1-2. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of oxaliplatin until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. At least 6 patients are treated at the MTD.

After completion of study treatment, patients are followed periodically.

Current Primary Outcome:

  • MTD based on the incidence of DLT as assessed by the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version (v.) 3.0 [ Time Frame: 14 days ]
  • DLT defined as any grade 3 or greater non-hematologic toxicity attributed to the combination of drugs in this regimen, despite maximal supportive care as assessed by NCI CTCAE v. 3 [ Time Frame: 14 days ]


Original Primary Outcome:

Current Secondary Outcome:

  • Safety profile as assessed by NCI CTCAE v. 3.0 [ Time Frame: 14 days ]
    Any incidence of adverse events will be recorded and classified according to body region and severity.
  • Tumor response based on PET or PET/CT scan [ Time Frame: From baseline to 6 weeks ]
    Wilcoxon rank sum statistic will be used to assess whether tumor response is associated with the change in the PET SUV value.
